Long-Range Sensor Communication.
Abstract
A performance study was conducted to determine the feasibility of direct long-range remote sensor communications without the use of relays. Of the propagation modes analyzed, HF ionospheric, MF.HF ground-wave, and forward meteor scatter, the HF ionospheric propagation mode is favored and performance predictions using this mode for digital message transmission are presented. The performance is given in terms of predicted message error rate and circuit outage under various conditions of range, frequency, hour, season, sunspot number and geographic location.
